to take care to select sufficiently.Ittakes about 1
minutefor clearing. Incase of losing PINcode,
thissubmenu is helpful for you.
3.5. IPEI
Thissubmenu shows you IPEI(International
Portable Equipment Identity) of thisGDC-345H.
3.6. SiteSurvery
Thissubmenu makes this GDC-345H to operate
as GDC-345TH CRS (Cell coverageRegion
Survey) tool for cell planning. Toexitfromthis
mode, pressC/Rbutton until ‘Idle state’is

Inthe submenu ‘1PARK ID’,you have to enter
the samePARKIDas that of GDC-345TBthat you
want tolock to. If a PARK IDis entered differently
from that of GDC-345TB thatis the Fixed Partof
CRS (Cell coverage Region Survey) tool, GDC-
345Hdoesn’toperate properly.Ifyou entera
wrong PARK IDyou can delete it by C/R button. If
you press the C/R button longer thanone second
youcan erase the whole entered digits and if for short pressing you candelete one

viewing the Appendix A. available PARK table of the GDC-345 CRStoolmanual.
Inthe submenu ‘2Warn Level’,you can determine alower RSSIwarning level. This
helpsan installernotice acell-coverageregion.
For instancethe value isdetermined as –80dBm
and GDC-345H goes farther beyond the region of
whichRSSI level is about –80dBm, then the
warning tone is generated. With this warning tone,
an installer can easily notice the cell-coverage
region. You can chooseany value from 60to 90
and the initialdefaultRSSI warninglevel is –
80dBm. Ifthis value isdetermined atsmaller than –80dBm, the warning tone will
be heard in the closer distancefromthe GDC-
345TB and versa.

RSSIlevel of dummychannel. DummychannelRSSImeasurementsurveys the
strengthof received dummy channel withwhichGDC-345TH is in synchronization.
The second line of LCDdisplays the dummymeasurement. First and second column
of third line indicates the RPN(Radiofixed Part Number)of synchronized GDC-
345TB.
Inthe submenu ‘4Traffic’,you can measure the
RSSIlevel of traffic channel. Traffic channel RSSI
measurement surveys the strengthof received
trafficchannel withwhich GDC-345TH is in
connection. The secondline of LCDdisplaysthe
traffic measurement. First andsecond column of thirdline indicatesthe RPN(Radio
fixed Part Number) of connected GDC-345TB.The RPNof GDC-345TBis fixed at (0
0). And thelastof thirdline displays the RSSIlevel of trafficchannel. For the most
part measured levelof traffic and dummy channel are nearly alike.
The nominal decision level bywhich cell-coverage boundary is settledis 80 dBm.
But for better voice quality it is safe to determinethecell-coverage
boundary by 70 dBm.
When GDC-335TH loses the connection withGDC-
345TB,one of the left LCD messages is displayed.
Andwhen the measured RSSI value is lower than
the already entered RSSIwarning level,warning
tone is generatedperiodically.
3.7. EnteringCellTool Mode
